Nightjar

The easiest way to find out if the nocturnal and well-camouflaged nightjar is about is to listen out for its distinctive 'churring' call at dusk. A summer visitor, it is most numerous in southern England.

Ynghylch

Arriving here in April and May from its wintering grounds in Africa, the nightjar nests on the ground on heathland and in young conifer woods. It is nocturnal, feeding on moths, flies and beetles. Amazingly well camouflaged, the nightjar is most easily spotted at dusk when the males can be seen displaying to females, flying around them and wing-clapping. Their distinctive 'churring' call is often given from a prominent perch.

Sut i'w hadnabod

The nightjar has cryptic, bark-like plumage that helps it hide among the undergrowth. Adults have flat heads, a small bill with a surprisingly large gape, and big eyes. Males have white patches towards the end of their wings and at the end of their tails.

Roeddech chi yn gwybod?

Many birds have a series of whisker-like feathers (called rictal bristles) around their beak. In nightjars, the rictal bristles are particularly long and obvious. Scientists still aren't sure of the exact role of these bristles, but think they may play a sensory role that helps birds that are foraging in low light levels.
